I don't see this one as much anymore. Two years ago it used to be a staple of almost every editing post.

"This project has already been through a couple of rounds of self­-editing" = so there's almost nothing left for you to do that you can charge me for.

Is it just me, or is self-editing something people just used to naturally do out of courtesy before asking anyone else to read their initial draft? I can't figure out when it became "a thing" you needed to announce to people like it was a sign you were on a higher plane of writerly consciousness.

Estate agents here (usually English - not always) will advertise a pile of stones vaguely resembling a building and call it an "umissable country project" - usually wildly overpriced and quite literally in the middle of nowhere - no electricity, water etc.
